1.Check the submersible gear box.

Submersible gearbox has high precision and good heat treatment, but it also has the phenomenon of gear teeth and the gear shaft is not axial clearance. We carried out a thorough cleaning of the gearbox and carefully examined gears, gear shafts, bearings. There is no pitting in the inner and outer ring and the surface of the roller, and the whole quality is good. The gears are smooth, no pitting, overlapping, normal backlash, no obvious wear on tooth profile. The radial and axial clearance are normal. Axial clearance is reasonable, hand wheel output shaft free flow, no interference, no abnormal sound. Therefore, the failure of the gearbox is eliminated.

2.Submersible mixer mechanical seal inspection

Mechanical seals are the most prone to failure of submersible fittings, often due to wear and tear of the mechanical seal failure, seal the cavity water. We first disassemble the mechanical seal assembly, which consists of two sets of mechanical seals, the skeleton oil seal, the output shaft, the bearing, the outer cover and the end cap and so on part to carry on the cleaning and the inspection, and inspects the bearing seat and the output shaft size, has not found. The mechanical seal is in place to eliminate the possibility of failure.

Submersible mixer is a equipment which can not be lack in sewage treatment plant, and widely used in industrial applications, its main work as we can hear it from its name, dive into the water carry out the mixing work.
We know that water resistance is very large, so the general low-power submersible mixer is very difficult to operate underwater, and poor working conditions in the local may also cause indirect short circuit, resulting in mechanical damage. So choose a stable diving mixer for future work efficiency is very important. Our submersible mixer per 500 square meters of volume to use 1 kilowatt power makes the motor speed at 60NM above, the relevant personnel to detect a small part of the small impeller fast-forward submersible mixer can not achieve this effect.

The motor windings of the submersible mixer are used in the aeration system to reduce the energy consumption of the system and increase the oxygenation to prevent the precipitation. According to process requirements, direct-coupled diving mixing can be equipped with shroud.
Mixing Series submersible mixer is suitable for the process of the need to maintain solid and liquid two-phase or solid, liquid, gas three-phase medium even mixing reaction place.

Urban sewage pump in pipeline is a kind of cleaning device, but the principle of pump is somewhat similar to the pump flow booster or a stirring device. And they all have in common a dedicated motor and impeller, energy transport through the motor so that the impeller to rotate and thus play a role in stirring and plug-flow, which is currently the main use of sewage pumps and submersible mixers mixer, to introduce the following click one of submersible mixer.
Generating means are stirring for mixing and subsequent filtration media played a role in the regulation when it comes to this mixer, in fact, the current submersible mixer is typical devices. The device we are not very clear, in fact, it is the use of some means of sewage in the pool, the main role is in the pool, on the media mixing and stirring, so that the media will not settle down. For discharging the medium of impurities is very meaningful thing. And this was stirred diving equipment, since the jet also has a certain effect, it is also known as submersible flow boosters. For sewage treatment subsequent steps, this submersible mixer is still needed, which is a manifestation of improving filtration and sewage.

The special installation system of submersible mixer can be installed and removed without discharging sewage tank.
When the pool depth below 4 meters is recommended to install a system. Diving depth of the submersible mixer can be adjusted vertically according to need, and show off in the horizontal rotatable about the guide rod maximum angle of rotation of plus or minus 60 ° lifting system base bracket and the lower bracket on connecting surfaces are used with the pool expansion bolts, without prepared hole. Installation system with two guide ropes substitute guide rod, with convenient transportation, site installation simple. This system avoids the fundamental cause transport guide rod bending and deformation thus affecting the normal use and improve the pool is too deep in deep case, since the guide bar mounting error caused by not properly lifting and so on. In the case of the cantilever pool roof installation conditions even more convenient and reliable operation.
When the customer orders, please provide the pool and pool depth H chart to determine the guide rod or guide wire size when the plant processing. Mounting system made of stainless steel (or carbon steel) manufacturing. In addition to lifting steel guide rods or guide base in install the system, more than one mixer can use one lifting device publicly.

Submersible mixer is applicable in the sewage treatment plant, which contains a dilute suspension of mud, sewage, industrial process fluids, etc., can create water, the stirring function to strengthen, not precipitation sludge in municipal and industrial wastewater treatment process played a very important role, is an important device.
Periodic inspection and inspection matters submersible mixer submersible mixer for regular inspection and maintenance to ensure that the operation more safe and reliable. Filling and changing the oil in the factory before the submersible mixer has been injected into the oil chamber of the right amount of oil, the oil needs to be replaced every year.
Oil change should be carried out in the following manner: The submersible mixer stand or on two levels with lift its travel, so that the oil chamber plug down, put a container designed to receive oil under the plug. Unscrew the drain plug (if the filling hole screw is loosened, the drain will be more convenient) lubricating oil discharged, and then washed with clean oil oil chamber, and then inject the right amount of lubricant at this time diving mixer needs to maintain a horizontal position . To replace the O-ring screw hole under normal circumstances, and then tighten the plug.
Diving mixer safety precautions before starting maintenance of the equipment, must be able to ensure that the submersible mixer and power cut off and there is no law was started some unexpected way. To avoid injury, pay attention to the mounting system special needs of the state of damage and wear components.To ensure stable performance of all components, or scroll down to ensure the situation does not occur, so as to avoid unnecessary damage to harm people or goods.

Sewage treatment is purification process that in order to achieve the sewage drain or meet water quality requirements which can be used again. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical, food and other fields, but also more and more into the daily lives of ordinary people.

Classification according to sources of wastewater, sewage treatment is generally divided into the production of sewage treatment and domestic sewage treatment. Production sewage including industrial sewage, agricultural runoff and medical sewage, and domestic sewage is generated everyday life, refers to a complex mixture of various forms of inorganic and organic, including: ①floating and suspended solids; ② gum and diffusion-like gelatinous substance; ③ pure solution.
According to the nature of sewage, water pollution has two types: one is natural pollution; the other is man-made pollution. Currently, man-made pollution is greater harm to the water. Depending on the contamination of water pollution can be divided into chemical pollution, physical pollution and biological pollution. The main pollutants are: ⑴ The discharge of untreated industrial wastewater; ⑵ discharged untreated sewage; ⑶ heavy use of agricultural waste water of chemical fertilizers, pesticides, herbicides; ⑷ stacked in the river industrial waste and garbage ; ⑸ soil erosion; ⑹ mine wastewater.
